The United Kingdom's departure from the European Union is just two days away - and Channel 4 are marking the impending exit with a documentary exploring the world of one of Brexit's chief engineers: Nigel Farage.

The divisive and vocal politician has been a permanent fixture in the Brexit debate, roving hugely influential in the Leave campaign's referendum victory in 2016.

His influence has waned in recent months, however, with Boris Johnson rejecting a Leave Alliance in the lead up to the 2019 December General Election.

Director Christian Trumble followed the 55-year-old over a course of five months as he tries to put his stamp on a final Brexit deal, while also charting his role on the 2016 Brexit referendum.

When is it on?

Farage: The Man Who Made Brexit is on Channel 4 on January 29 at 9pm.

The documentary will be available to stream online on All 4 following its transmission on Wednesday night.

What is it about?

Filmed over five months, Farage: The Man Who Made Brexit follows the leader as he attempts to build on his historic success in May 2019's European elections.

The documentary captures the inside story of Farage's doomed attempt to persuade Boris Johnson to join a Leavers' Alliance with him, and also charts Farage's influence in changing British politics in the wake of the 2016 EU referendum.

With racism returning to haunt the party and plummeting poll ratings, is December 2019's general election the event that finally persuades Farage that the UK will never buy what he is selling?

Or can he claim victory with a brand-new right-leaning Tory government that supports much of what he stands for?

Farage is outspoken throughout, taking aim at Boris Johnson adviser Dominic Cummings at one point, stating: "I mean that horrible nasty little man who goes around calling Banks and I toxic. He's got to go. Dominic Cummings must go."

What have critics said?

Guardian writer Ammar Kalia praised the documentary, claiming Trumble's portrait of Nigel Farage "not as a pint-drinking caricature in a pinstripe suit, but rather a canny political operator" is a convincing one.

Paul Whitelaw of the Courier described the documentary as "a hilarious, own goal".

He goes onto claim that the Brexit Party leader comes across as "a sad, petulant, thin-skinned, gravy-stained opportunist."
